A ROOM TO EXPLORE
The AI room.
Watch Robot Nano Hand perform five gestures on the last right-hand desk. Inspect its moving joints, rearrange the room, and explore the AI lab.

Joint angles · simulated
Angles follow the animated model. MCP is the knuckle, PIP the middle hinge, DIP the fingertip hinge; the thumb has an IP hinge. Spread moves fingers sideways.
| Joint | Angle |

Printed hand & forearm
Ivory shell panels, segmented fingers, exposed steel hinge pins, a tapered forearm and a black tape band follow the photographed variant. The native model has editable finger flexion and spread, thumb opposition, and wrist pitch. Its dimensions and joint limits are modeling estimates.
Gesture demonstration
Open palm → fist → OK → peace → index pointing. Each pose holds for two seconds and blends to the next over one second. Finger segments bend together to suggest tendon actuation.
Reference hardware
The original Nano Hand uses tendon-driven digits with knuckle spread and a pitched wrist, totaling 11 actuated degrees of freedom. This model articulates 20 visible joint axes. The photographed variant’s electronics are unconfirmed; this scene runs scripted motion without live vision or hardware control.
A scripted sorting demonstration: two green, two pink and two red cells move into matching holders. Each batch repeats after a short pause. Sorting continues while you inspect.
Printed structure & joints
Five positioning joints and a servo-actuated gripper follow the original SO-101 geometry and joint limits. Blue printed links, the perforated mounting flange, fasteners and exposed wiring match the photographed homemade build.
Servos & controller
The standard LeRobot SO-101 follower uses six Feetech STS3215 bus servos. The model includes their housings, horn screws, three-wire leads and an exposed rear controller board. Exact electronics fitted to this homemade variant are unconfirmed.
Custom gripper fingers
Extended translucent fingers with visible printed ribs reproduce the custom jaws in your photos. The articulated jaw closes around each cell; the cell follows the grip until placed in its color holder.
Depth camera & demonstration
The separate depth camera looks down from a white segmented post with a green bracket and spring clamp. Its product model is unconfirmed. Sorting is pre-animated; the walkthrough does not run live vision or control physical hardware.
The robot keeps following its predefined route while details are open. It waits for furniture to clear its path. Your walking controls pause while you inspect.
Compute & drive
Raspberry Pi 5 runs ROS 2. Two Dynamixel XL430-W250-T servos drive the orange wheels; two passive casters support the chassis. The U2D2 interface connects the motors.
LiDAR & depth camera
The raised Slamtec A1 LiDAR scans the surroundings. The front Intel RealSense D435i supplies depth imagery. An Adafruit BNO055 IMU measures orientation.
Mapping & navigation
The project includes Cartographer mapping, AMCL localization and Nav2 path planning. An extended Kalman filter combines IMU readings with wheel odometry. Keyboard teleoperation and Gazebo simulation are also provided.
Chassis & this photographed build
Two perforated printed decks, six 35 mm spacers, PLA rims and TPU tires form the platform. Three 18650 cells supply power. The blue enclosure and metal sensor cap follow your photos; the repository does not identify that extra sensor.
Dimensions describe the modeled assembly, not a measured inventory item.
